Definition
In terminis is a Latin maxim meaning "in express terms," "in so many words," or "in the very terms." It is used to indicate that something is stated, decided, or established directly and explicitly — not by inference, analogy, or implication. When a court says a point was not decided in terminis, it means the earlier authority did not expressly address the issue, even if a ruling on it might be inferred. Conversely, to say that a rule or holding exists in terminis is to assert that the text itself, or the decision itself, states the proposition outright.
Common Confusion
In terminis is sometimes conflated with in terms, its near-literal English translation, but the Latin phrase carries a precise technical weight that the English phrase lacks. "In terms" in casual legal writing might mean merely "in substance" or "with respect to." In terminis, by contrast, signals explicit textual or decisional specificity — the difference between a rule announced and a rule implied. It is also occasionally confused with in haec verba (in these exact words), which is narrower still: in haec verba refers to verbatim reproduction of language, while in terminis denotes express statement without necessarily requiring word-for-word quotation.
Why It Matters in Research
The phrase appears most often in older English and American common law authorities when courts are distinguishing binding precedent from persuasive analogy. A court citing a prior case in terminis is asserting that the earlier decision directly and expressly resolved the precise question at hand — a stronger claim than saying the prior case is "on point" or "analogous." Researchers reading historical opinions should treat in terminis as a signal that the author is making a precision argument about the scope of a precedent, not merely citing authority generally.
The phrase also appears in settlement and conveyancing contexts (as Burrill's reference to settlement cases suggests), where it marks the difference between rights or conditions expressly stated in an instrument versus those arising by construction or implication. In property and equity sources, this distinction could be outcome-determinative: courts construing instruments narrowly would refuse to find obligations or grants that did not exist in terminis.
For corpus researchers: the frequency of this phrase drops sharply after the mid-nineteenth century as American legal writing increasingly shed Latin maxims in favor of English equivalents. When you encounter it in post-1870 sources, it often signals a court or author self-consciously invoking older common law tradition for rhetorical weight. In earlier sources — colonial-era to antebellum — it may appear without explanation, assumed to be familiar to the reader.
Historical Dictionary Support
Burrill's Law Dictionary defines in terminis simply as "In terms," with a citation to Burrill's Settlement Cases at page 286. The entry is skeletal, offering translation without context — characteristic of Burrill's treatment of Latin maxims that were, at the time of compilation, considered self-explanatory to the trained legal reader. The citation to settlement cases (a specialized body of English poor law decisions concerning parish settlement of paupers) confirms that the phrase had practical application in instrument-and-record interpretation, not merely in judicial rhetoric about precedent.
No other source dictionaries are available for comparison in this entry, but the phrase appears in Black's Law Dictionary across multiple editions with consistent meaning, and its usage in historical English reporters (particularly in equity and common law courts through the eighteenth and early nineteenth centuries) aligns with Burrill's sparse definition. The phrase's meaning has not evolved — it has simply become less common.
Jurisdictional Note
In terminis is a feature of common law legal discourse and appears primarily in English, American, and other common law jurisdiction sources. It carries no specialized meaning that varies by jurisdiction; the variation researchers will notice is temporal, not geographic — it is a phrase of older legal writing that has largely been replaced by plain-English equivalents.
